I have recently started searching for a job again. Of course in the US your LinkedIn profile can be very valuable in the job search, and I updated my profile. I have also heard about another professional network called Xing which seems to be popular in the German speaking part of Europe (from what I've read). I'm curious about how or if these sites are even used in Switzerland.

Have any of you had any luck finding a job with Xing or LinkedIn in Switzerland? Do Swiss professionals even use such networking sites?

I've found that the German-non German gap between Xing and Linkedin is narrowing.

From my own experience more of my Swiss and German colleagues are on Linkedin now than Xing. I ended up deleting my Xing account as I found it brought me nothing, had a horrible interface, and wasn't as engaging with articles and the like as Linkedin is.

I always found my jobs over xing or linkedin. Head hunters checked them often. Lets say in marketing and sales, they know that people move every 2-3 years and get in touch with you with new job offers.
Xing helped me more as i have a german/french/international profile.
Linkedin is more for english speaking people.
